CALL FOR PAPERS
Special Issue on International Journal of Autonomous and Adaptive Communications Systems (IJAACS)
Cognitive Radio Systems
Cognitive radio is a highly promising communications paradigm to address the spectrum insufficiency problem.
Currently, different wireless systems are regulated by a fixed spectrum assignment strategy. This policy partitions
the whole spectrum into a large number of different ranges. Each piece is specified for a particular system. This
leads to undesirable situation that some systems may only use the allocated spectrum to a limited extent while others
have very serious spectrum insufficiency situation. In addition, wireless channel is inherently characterized by
unreliability. This may lead to context dependent large-scale shadowing or small-scale fading. Furthermore, the
future generation broadband wireless networking promises to provide multimedia services under the co-existence of
heterogeneous networks. These challenges and requirements result in the problem of scarce spectrum even worse;
and motivate new technologies to efficiently use spectrum. Cognitive radio is believed to be a highly potential
technology to address these issues. It refers to the potentiality that the systems are aware of context and capable of
reconfiguring themselves based on the surrounding environments and their own properties with respect to traffic
load, congestion situation, network topology, and wireless channel propagation etc. However, cognitive radio
wireless systems are still in the very early stage of research and development. There are a number of technical,
economical, and regulatory challenges to be addressed.
The aim of this special issue is to present a collection of high-quality research papers that report the latest research
advances in this field from physical and network layers to practical applications. Topics of interest include, but are
not limited to:
• Signal Processing
• Security
• MIMO
• Cognitive multi-hop networks
• Channel coding
• Spectrum management (e.g. spectrum
sensing, spectrum sharing)
• Resource management
• Model and performance evaluation
• Mobility management
• Game theory in cognitive radio
• Energy management
• Standards, e.g. IEEE 802.22
• Cross-layer design and optimization
• Regulation and business model
• Cooperation schemes
• Testbed, experiment, implementation,
• Routing
standards, and practical applications
• Medium Access Control
• QoS provisioning
Submitted papers should not have been previously published nor be currently under consideration for publication
elsewhere. Authors should follow the International Journal of Autonomous and Adaptive Communications Systems
